摘要: age, but there were no significant differences among rookeries. Male and female pups grew (in mass, standard length, axillary girth) at the same rate. Body mass length increased a faster rate for in Aleutian Islands western Gulf of Alaska (0.45−0.48 kg/day 0.47−0.53 cm/day, respectively) than southeast (0.23 0.20 cm/day). Additionally, girth (0.59 cm/ day) v(0.25 Our results indicate greater maternal investment male during gestation, not early lactation. Although pup growth occurred rookeries, was evidence that sea lions their nutritionally stressed area
